 * is relatively expensive as it involves walking up the hierarchy twice for
 * every IO. Thus, if iolatency is not enabled in any cgroup for the device, we
 * want to disable the in-flight tracking.
 *
 * We have to make sure that the counting is balanced - we don't want to leak
 * the in-flight counts by disabling accounting in the completion path while IOs
 * are in flight. This is achieved by ensuring that no IO is in flight by
 * freezing the queue while flipping ->enabled. As this requires a sleepable
 * context, ->enabled flipping is punted to this work function.
